| 1. | Standards for fresh concrete 新拌混凝土标准 |
| 2. | It is very important to choose a proper mix technology to make pumice concrete 其混凝土配制工艺要求必须适当处理好骨料的早期吸水对新拌混凝土性能的影响。 |
| 3. | Method of test for variability of freshly mixed concrete by measuring mortar and coarse aggregate contents 通过测量灰浆和粗骨料含量测定新拌混凝土变化性的试验方法 |
| 4. | Testing concrete - method for determination of density of partially compacted semi - dry fresh concrete 混凝土试验.第129部分:部分压实半干新拌混凝土稠密度的测定方法 |
| 5. | At the same time , the non - contacting electrical measurement device is used to monitor the electrical property of fresh concrete 同时利用无电极电阻率测定仪来研究新拌混凝土的电学性能。 |
| 6. | Concrete , mortar and grout admixtures . measurement of the percentage of entrained air in fresh concrete using an air meter 混凝土砂浆和灰浆添加剂.气量计测定新拌混凝土内封闭空气的百分比 |
| 7. | To assure the workability such as fluidity , ability of filling , ability of resistance to segregation of the fresh self - compacting concrete , numerous tests have been done 进行了大量的优化配合比的试验,使新拌混凝土具有更优良的流动性、填充性和抗分离性。 |
| 8. | Studying surface tension of different concrete additives is helpful for additive choice in application and critical micelle concentration ( cmc ) is reference for the proper dosage of additives 在混凝土中掺入适量的ns 、 pn或ss可以降低新拌混凝土的振动粘度系数。 |
| 9. | The electrical resistivity curves of fresh concrete have the same developing tendency . they can all be divided into three stages : dissolving period , competition period and setting and hardening period 新拌混凝土的电阻率曲线具有相同的发展趋势,都可以划分为三个阶段:溶解阶段、竞争阶段和凝结硬化阶段。 |
| 10. | The borderline w / b ratio for fly ash and silica fume concrete is about 0 . 36 and 0 . 4 , respectively . 5 ) polypropylene fiber can make them quite effective in the suppression and stabilization of microcracks in fresh concrete matrix 7 )在室外太阳辐射、 8m / s风速条件下,新拌混凝土的塑性开裂与水灰比有关,水灰比界限约为0 . 4 。 |
